some one help me create new tilemap like "BattleFarm Extension maps file xml"? i'm using OpenSpace, and export, it's not format like (...\deploy\extensions\battleFarm\BattleFarmMaps.xml) file. Thank you!

There's no editor to generate the BattleFarm maps. You can just use a simple text editor to modify them or create new ones.The OpenSpace Editor only generates the OpenSpace maps which, as I said, have nothing to do with BattleFarm.
